L9637
Monolithic bus driver with ISO 9141 interface
Features
■ Operating power supply voltage range
4.5 V ≤ V_S ≤ 36 V (40 V for transients)
■ Reverse supply (battery) protected down to
V_S ≥ -24 V
■ Standby mode with very low current
consumption IS_SB ≤ 1 mA @ V_CC ≤ 0.5 V
■ Low quiescent current in off condition
IS_OFF = 120 µA
■ TTL compatible TX input
■ Bidirectional K-I/O pin with supply voltage
dependent input threshold
■ Overtemperature shut down function Selective
to K-I/O pin
■ Wide input and output voltage range
-24 V ≤ V_K ≤ V_S
■ K output current limitation, typ. I_K = 60 mA
■ Defined OFF output status in undervoltage
condition and V_S or GND interruption
■ Controlled output slope for low EMI
SO8
■ High input impedance for open V_S or GND
connection
■ Defined output ON status of LO or RX for open
LI or K inputs
■ Defined K output OFF for TX input open
■ Integrated pull up resistors for TX, RX and LO
■ EMI robustness optimized
